1. An impactor system for impacting a base of a shoulder implant into a humerus, the system comprising:
a housing having distal stabilizer configured to contact a proximal resected surface of the humerus, the distal stabilizer defining an open space; and
an impaction member slidably received within the distal stabilizer, the impaction member having a proximal surface and a distal surface with a distal connection mechanism extending therefrom and adapted to contact the base of the shoulder implant,
wherein the impaction member is movable from a first proximal position in which the base of the shoulder implant and the distal surface of the impaction member, when connected to the impaction member, is positioned within the open space defined by the distal stabilizer, to a second distal position in which the base of the shoulder implant and the distal surface of the impaction member, when connected to the impaction member, is positioned at least partially distal to the open space defined by the distal stabilizer.
